(a) The decoding error \(P_{\epsilon }\) is compared for several values of \(L_{0}\) from structures containing L pairs of items for two values of N and two values of \(\alpha \). (b) \(\text {SNR}^{-1}\) v. L. For each value of \(L_{0}\), \(l_{c}\) is given by the value of L where \(\text {SNR}^{-1}\) diverges from the line corresponding to the original structure, which is marked for each value of \(L_{0}\). (c) \(\left( \text {SNR}/\text {SNR}_{0}\right) ^{-1}\) v. \(\frac{L}{L_{0}}\) where \(\text {SNR}_{0}=\frac{N}{L}\). For all figures, \(T=20\) parallel updates are used in memory retrieval and the average is performed over 10, 000 memories. The dictionary is fixed to \(D=30N\).
